Not to belabour the point of my original question….

if I wanted to stick with 215/45/17 up front, and 245/40/17 in the back (I really like the look of the wheels I have), with 18.8 bars up front what might be the optimum bar diameter in the rear be for a car that will probably only ever be road-driven? Stock anti-roll bars.

I don’t have to stick with 27’s in the back; particularly if they are going to make the car less user-friendly.

I’d rather make something closer to right decision now. Budget is not a primary concern.
